Specification forming part of Letters Patent No. 203,533, dated May14,1878; applicationfiled January 10, 1878.

To all whom it may concern:

Be it known that I, HENRY I. CARVER, of

Ludlow, in the State of Massachusetts, have invented a new and usefulImproved Combined .Butter iworker and Mold; and that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, making apart of this specification, and to theletters of reference marked thereon.

My invention relates to a device for working butter, for the purpose ofextracting all the buttermilk, and also to mold the butter intoconvenient balls for the table and for market; and it consists of a trayhaving its front end curved in a vertical direction, and a lever pivotedand moving upon a rod having its hearings in blocks which slide ingrooves in the upper edges of the sides of the tray. The lever has aplunger attached thereto for working the butter, which plunger may bedetached therefrom, and a mold attached in its place for molding thebutter into small balls. The tray rests upon a box or closet connectedwith the legs, and arotating block secured on eccentric bearings in thelegs serves to tilt the tray to the desired inclination to cause theliquid to run from the tray through an orifice into a suitablereceptacle, all which will be more fully described.

Figure I is a perspective view of my invention with the mold attached tothe lever for molding the butter into balls. Fig. II is" a longitudinalvertical section of the same. Fig. III is a perspective view of thelever with the plunger attached thereto for working the butter. Fig. 1Vis a longitudinal vertical section of the plunger made hollow, and Fig.V is a vertical section of the mold with the point inserted for pushingout the butter from the mold and stamping it.

In the drawings, A represents the tray, havin g two parallel sides, andwith the front end curved upward, like a semi-cylinder, arrangedhorizontally across the end of tray A, with the concavity inward, asshown at B, and with a groove, a, made in the exterior of each side A atits upper edge, in which slides the block a, one in each groove. Thiscurvature of end B causes the butter, as it is crowded into said theendof the lever against the rod 0. thumbscrew, h, turned through the lever,secures a piece, 6, thereto; and upon the lower end, to roll over upwardand backward into the tray again. These blocks are connected by the rod0, which passes through the end of the lever I), having a set-screw, 0,turned into A end of this is fitted the mold f, of the desired form anddepth, a rectangular form being deemed-the best for a rectangular tray,which mold issecured in place by a hook and staple or other convenientmeans. mold f, on the side toward concave end B, is made convex, tocorrespond with said end and completely fill the same, thereby avoidingthe accumulation in said concavity of particles of butter beyond thereach of said mold. The same side or face of the plunger hereindescribed should be similarly shaped. The front end B of the tray ismade curved in a vertical direction, so that, in either working thebutter or molding it, the lower front corner of the plunger or the moldwill, if raised nearly to the front upper edge of the end B, pass alongdown to its lower edge in contact with the inner side, and clean off anybutter which may have collected thereon.

The tray rests on the top of a closet, D, and is secured thereto withhooks and staples m and said closet is provided with pieces E and F, andablock, m, between the pieces E, is provided with eccentric journals atthe ends, which have their hearings in the pieces E, so that when saidblock is turned with one side downward, that lower side bears upon thefloor, raising the pieces E from the floor, so that the bottom of thetray will have the proper inclination to cause the liquid in the tray torun out the orifice i; and by turning the block, with its opposite sidedownward, the pieces'E will then rest on the floor.

The plunger I is of a length equal to the width of the tray inside, sothat in working the butter it may extend across the tray from one sideto the other, and operate upon the butter the whole width of the tray. Iprefer to make the plunger hollow, so that in cold weather warm watermay be poured into it at the orifice 0, and a stopper put in, wherebythe plunger may be somewhat heated and warm The outer face of thebutter, making it easier to work; and in warm weather cold water may bepoured in to cool the butter.

When the plunger I is attached to the lever the butter is worked byraising the lever and forcing the plunger down into the butter, theblocks a sliding along in their guides, so that the plunger may reachall parts of the tray. After the butter is thoroughly worked the plungeris detached by turning out the screw h and attaching the piece 6 andmold f. By Working the lever in a vertical direction and pressing themold down into the butter all along the tray, the mold is filled with asolid mass of butter.

The lever b may be set in a position on its fulcrum-rod 0, so that themold may be pressed down into and take up all the butter along theentire length of one side of the tray, and then be moved along itsfulcrum-rod a, so that all the butter along the other side of the traymay be molded. Each time the mold f is filled with butter it isunfastened and removed from the piece 6, and the print f (which is ablock fitted to slide through the mold and ornamented on its lower face)is inserted in the top of the mold and pressed down against the top ofthe butter, which prints or ornaments the top of the ball, and forces itout of the mold ready for the table or market.

I am aware that butter-workers having a plungerattached to avertically-moving lever have heretofore been made and used, and I do notclaim the same nor any part thereof, irrespective of my construction andarrangement of the same; but,

Having described my invention, what I do claim as new is- 1. Incombination with a pivoted longitudinally-movable lever and a plungeroperated thereby, a tray having one end, B, curved up- Z vard,substantially as and for the purpose set orth.

2. In combination with a pivoted longitudinally-movable lever and aplunger operated thereby, a tray having an upwardly curved end, B, theopposing faces of said plunger and said end B being made correspondinglyconvex and concave, substantially as and for the purposes set forth.

3. In a butter-worker, a hollow plunger, provided with an opening foradmitting water, substantially as and for the purposes set forth.
